くできる。As described above, the anti-vibration support device according to the present invention includes a mounting board on which at least a pair of leaf spring members constituted by a plurality of leaf springs of different lengths are erected, and a mounting board located on the board and engaged with the leaf spring members. Since it is composed of a pillar-shaped vibration isolating rubber member that is stopped, and a cap body that is attached to the upper surface of the rubber member and has a mounting rod, the vertical spring constant of the vibration isolating rubber member can be made sufficiently small. The vibration isolation effect during compressor operation can be increased.
